Abstract
In this paper, we report the formation of extremely sharp (Quality factor Q~ + ∞) FR in a single layer of dielectric nanorods with perturbed periodicity. The interference between the broadband Fabry-Perot (F-P) resonance and defect induced dark mode results in refractive index sensitivity (S) of 1312.75 nm/RIU and figure of merit (FOM) of 500, offering an excellent platform for biological sensing and detection.
摘要
在本文中，我们报道了在具有扰动周期性的单层介电纳米棒中形成了极尖锐（品质因数Q~ + ∞）的法诺共振（FR）。宽带法布里-珀罗（F-P）共振与缺陷诱导暗模式之间的干涉导致折射率灵敏度（S）为1312.75 nm/RIU，品质因数（FOM）为500，为生物传感和检测提供了一个优异的平台。
